I have a son who will be 30 this year on September 5th. He has been addicted to meth since he was 17. I believe he is bi-polar like me but also refuses help. The best advice I can give you is don't enable her. I did this with my son and 11 mos ago he finally stole from me and I haven't spoken to him since. It is good that you don't stick around too long when she is displaying inappropriate behavior. I pray that she will get help! I also pray for you, as a mother, that you can find some peace and happiness in your life!
